PIF MIL

Antiparasitic filters generally operate by impedance mismatch within a given frequency range.

The insertion loss of a filter in a supply or transmission circuit is defined as the ratio between the voltage values occuring at the line terminal leads immediately after the insertion point, before and after insertion.

Different standards specify the attenuation measurement possibilities in asymmetric (common mode) or symmetric (differential mode)
attenuation, measurements performed on load or no-load circuits.

The following standards are applicable :

• Standard GAM T 21
• Standard MIL STD 220 C
• Standard CISPR

The insertion loss performance is specified, measured according to the standard GAM T 21 or MIL STD 220 C in no-load conditions under an impedance of 50. 

This measurement enables to check the compliance of the manufactured batch and to compare certain filters.
The real efficiency of a filter on an equipment can only be obtained by disturbance measurement taking into account the source and operating impedance.

For signal or data transmission filters usually defined in matched impedances, attenuation in the pass-band is measured according to the standard MIL 18327 E.

These capacitors are ideal for industries requiring high reliability, such as:

• Aerospace and aviation
• Defense and military equipment
• High-performance industrial electronics

MIL specifications are publicly accessible via government websites like www.dla.mil/Land-and-Maritime 

Exxelia also provides guidance to help you select the right components for your projects.

• Long operational life and low failure rates.
• Strict quality assurance processes validated by military standards.

Exxelia's MIL-qualified capacitors comply with key specifications such as:

• MIL-PRF-39006: Wet tantalum capacitors for high-reliability applications.
• MIL-PRF-55514: Film capacitors for DC and AC circuits.
• MIL-PRF-83421: Metallized plastic film capacitors.

Exxelia offers capacitors with established reliability, achieving failure rates as low as 0.001% per 1,000 hours (S level) at a 90% confidence level. Other available levels include M (1%), P (0.1%), and R (0.01%).

Exxelia manufactures its MIL-qualified capacitors in accordance with all relevant military specifications. Capacitors are tested, marked, and validated to meet operational parameters outlined in MIL standards such as MIL-PRF-39006 and MIL-PRF-55514.

MIL-qualified capacitors meet stringent military specifications (e.g., MIL-PRF and MIL-STD standards) ensuring high reliability, durability, and performance in critical applications like aerospace, defense, and industrial electronics.

MIL/DSCC-qualified capacitors are passive components that meet military (MIL). These certifications ensure high reliability and performance for aerospace, defense, and other demanding applications.

Film and mica capacitors offer excellent stability, low dielectric losses, and high reliability under extreme environmental conditions. They are often preferred for high-frequency, high-voltage, and high-temperature applications.

Exxelia's MIL-qualified film and mica capacitors comply with standards such as:

• MIL-PRF-83446 (Mica capacitors)
• MIL-PRF-55510 (Polyester film capacitors)
• MIL-PRF-87217 (Polypropylene film capacitors)

MIL-PRF (Performance Specification) is a military qualification defining performance requirements. DSCC specifications are managed by the Defense Logistics Agency (DLA) and often reference MIL standards while including additional performance parameters or screening processes.

These capacitors are widely used in:

• Military and commercial aerospace systems
• Radar and RF applications
• Power electronics and energy storage
• Avionics and electronic warfare systems

The operating temperature depends on the specific capacitor type but generally ranges from -55°C to +125°C or higher, depending on the MIL specification.

Exxelia follows rigorous manufacturing and screening processes, including:

• 100% electrical testing
• Burn-in procedures
• Environmental stress screening (ESS)
• Lot acceptance testing (LAT)
